Bead caps allow you to fix pearls, beads or really, anything you make onto a chain, cord, etc.  You can use one as a center piece, or spaced for a chunkier look.  You can bunch them together to look like grapes.  A fun gift is a gemstone or pearls key ring - not something seen everywhere.

Press the legs of the bead cap to adapt to any shape, then simply bond on with glue or epoxy.

4 prongs, 5.5 mm length prongs.  Fits 5-7 mm bead, but I have used these on larger stones, too.
